(57) [Problem] To provide a photosensitive resin composition excellent in sensitivity, adhesion, resolution, plating resistance, and tenting property, and a photosensitive element using the same. SOLUTION: Polymer containing carboxyl group (A), a compound having at least one or more ethylenically unsaturated groups in the molecule (B), in a photosensitive resin composition comprising a photopolymerization initiator (C), at least one or more as a component (B) Methacrylate compounds having an ethylenically unsaturated group (B1) contains 60% by weight or more based on the whole component (B), and component (C) is 0.01 to 20 parts by weight based on 100 parts by weight of the total of components (A) and (B). Further, as the component (C), the lophine dimer (C1) is 2 to 5 parts by weight based on a total of 100 parts by weight of the components (A) and (B), and triphenylphosphine (C2) is 0.1 to A photosensitive resin composition containing 2.0 parts by weight and a photosensitive element using the same. |
